In this short excerpt from a 2004 interview, Jules at 93 waxes nostalgic about his days at Camp Kinderland.
To see the entire interview you can obtain the DVD of his 1948 film “The Naked City” and checkout the extra “Jules Dassin at LACMA” (Los Angeles County Museum of Art).

A note from Hershl Hartman.

Julie Dassin was a member of the left-wing, avant garde Yiddish theater ensemble,
ARTEF (Arbeter Teyater Farband - Worker's Theater Association),
a number of whose members went on to major roles on Broadway and in Hollywood.
He spent at least one summer in the mid-1930s on the adult side (not yet called Lakeland)
of Camp Kinderland as part of the cultural staff.
His performance there (1937?) in "The Bishop of Munster,"
portraying a Catholic churchman who had spoken out early against the Nazis,
was caught by Margaret Webster, about to launch her career as a major director of
Shakespearean and other classical dramas. Webster immediately recruited Julie for her
fledgling company. Incidentally, Webster's greatest triumph was the longest run of a
Shakespeare production in Broadway history: 296 performances of Othello, starring
another friend of Kinderland, Paul Robeson.
